As ericthered notes, generally speaking every +1 modifier for a DnD stat corresponds to a +1 to the stat itself in GURPS (DnD Str 11 is +0, so roughly GURPS ST 10; DnD Wis 17 is +3, so roughly GURPS Per 13 and Will 13).

As a long time GM of D&D (going back to AD&D1) and GURPS (1986) I would disagree with much of that especially for the real early versions where a sword did the same amount of damage if you swung or thrust it.

More over since D&D uses a d20 for hinting and many other dice for damage while GURPS uses a d6 a +1 in D&D does not equate to a +1 in GURPS

The D&D to GURPS sheet (which in print form goes a back to late 1980s). Because of the many variations it glosses over the differences and "cuts to the chase" and even then it is long.
